At tire shop...need an answer

[Fipp]

Am at discount tire now watching tires be changed.
One at a time ...no jacks used.

Taking the old 15” Goodyear marathons off and replacing with 15” Goodyear endurance tires.
Discount tire guy says the endurance tires should be torqued at 100 ft lbs.
The marathons were torqued at 110 ft lbs.

Why would the torque be different on the new tires if it’s the same wheel and the same size tire?

Just want to the sure as I had to battle to not get them to use jacks ..and want to be sure they are right about the torque

Thanks

The online owner's manual for your 2016 Flying Cloud is located at https://cdn.airstream.com/wp-content...manual-148.pdf. On page 4-4 the wheel torque for aluminum wheels is given as 110 ft-lbs. The steel wheels are torqued to 100 ft-lbs.

The torque is set for the wheels and their lug nuts. The tire has nothing to do with it. His book is probably wrong. Use your own torque wrench to set and check it after you leave, never to return.

Make sure he hand-torques the lugs with a calibrated torque wrench, not an air wrench and one of those “torque stick” gadgets that will possibly ruin your wheels.

I don’t trust too many tire busters to do it right, obviously.

This is spot on. Nothing more to be said. 110 lbs is the correct TQ.

You've got problems if they aren't using Jack's. How the heck do you do that?
Lift on the frame between the wheels. 100 pounds torque if alloy wheels. 80 psi will rattle your rivets.... Suggest 70 psi.
Good luck!

Something like this likely used.

I am having them torqued at 110 ft lbs just like I had the old ones ..per the manual.

Any other comments or advice is always welcome as I continue to learn each day about something new!

Thanks!!

Make sure they don't overinflate to "max pressure" or you could have problems. You should check your scale weights and adjust to Goodyear Endurance PSI chart for your AS weight...I had popped rivets and other hinge issues when I got mine installed last summer, until I adjusted air to 50-55PSI per the chart. Hope you like them!

“Trailer aid plus”by camco is being used. Doing one tire at a time.

I spent hours reading about horror story’s when jacks were used and trailers damaged....right here on this forum!
No jacks for me!

[AtomicNo13]

I wasn't thinking of ramps.... My mind's eye saw the tire dude ripping wheels our from under!

For sure! Inflating to 75 for now . I have he gye psi chart and still need to do my scale weights sometime soon. Probably reduce psi then accordingly.
Thanks

I will recheck the torque for sure just to satisfy myself ! He is hand tightening torquing the way I told him!!
Actually they have been pretty good meeting my requests

You’re doing it right. I did the same exact process with the trailer aid, one tire at a time, they hand tightened my (new McGard) lug nuts (I brought with me) to 110 and I rechecked with my own torque wrench after a 30-40 mile trip back to the storage yard.

I also posted a thread here somewhere about the pressures in the new GYEs. At 65 PSI, I wasn’t happy with the rise of temp and pressure and went to 70 and felt it was more in line with expectations. I may take them to 72 but probably not much higher. 70-72 is way more than I need for 6000# on the axles but I’m not getting any damage in the trailer and I’m comfortable with what I’m seeing on the TPMS. All good - your mileage can and will vary. Good luck!

Question for you.....If you only want to run 50-55psi why not run a LR C tire then????

[ROBERT CROSS]

They only give a maximum torque spec to save the wheel from damage, what is the minimum acceptable?
For fifty years I have been torque sticking with various 'impact' wenches, not one lost or damaged wheel... steel, alloy or aluminum.

Keep the mating surfaces clean, tighten in sequence, and the threads clean & dry.
For the AS I torque to my... 'can I get it off torque?'
TETO

BTW...you don't check the torque, you loosen and re-torque.
Threads tighten both ways.

Mine were inflated at 70PSI and I only towed 45 miles home thru the mountains then maybe a 1000 miles or so on next weekend camp trip. We noticed one rivet out, then my wife spotted another. Then we had a closet door with attached mirror, on the floor, held on by the bottom hinge only, when we arrived at our camp destination; where the screws holding the hinges had pulled out. We reinstalled toothpicks and gorilla glue, but also noticed the cabinet in the bathroom also had come loose at the hinges. Going home, the shower door came off the extrusion and was hanging...that's when I started looking at the Forum for help and adjusted to 50-55PSI per my scale weight. Next 10K miles or so we have had no issues at all, MT back to TX... Wish someone would have mentioned this to me prior to going home with the 70PSI settings from Discount Tire. Some folks here swear by the "max pressure" stickers, but read the chart and check your weights when you can on a cat scale.

After you have both the L & R wheel(s) weight, go home, grab a tall cold one and a comfortable chair.

Here is the read...

Search endurace and there will be a ton of results. IMO, the above is the most comprehensive.

Very sound advice from tireman9 and capri racer both extremely knowledgeable and in the tire industry re psi, ST speed rating and a solid safety margin.

I have a bambi with around 25k+/- miles on the GYE's and run them at 75 PSI based on my load and desired safety margin. Your math and your desired safety margin will determine your psi.I

I have never had 70+psi cause any damage.👍

Over rated WD/stiff ride, bad axle...yep.

Good to know! I’ve never done it that way - always just checked in tighten mode...

I’m feeling thick for not understanding threads tightening both ways.... [emoji55]
